This looks good ...

... Fame: from the Bronze Age to Britney by Tom Payne.

There's a review here and another one here.

Have you ever lamented the modern tendency to worship celebrities and indeed to make celebrities out of people with no discernible talent? Well apparently we've been doing it since the dawn of civilization, and it doesn't reflect too well on us. Tom Payne teaches classics and he knows his stuff, and cleverly shows the connections between the past and the present, even comparing the deaths of rock stars to human sacrifice.

As an avid reader of Heat myself, I must get this book.
